Abstract

Self-supporting unit element staircase consisting of linking elements of steel tube shaped by bending into a U-form and which lie at right angles to the line of the stairs. These linking elements are connected together at their upper, open ends by means of handrail parts, which are also of steel tube and have been shaped by bending and which have a coupling sleeve welded on transversely at one end. At their lower ends, the linking elements are connected together by means of the steps, which have pipe clamp fittings at their four corners. Two different step shapes permit every desired form of flight of stairs to be constructed.

Description

Die Erfindung betrifft eine selbsttragende Elementtreppe, vorzugsweise eingesetzt als Außentreppe, wie sie sowohl als Begehungstreppe in Industrieanlagen als auch als Brand- Fluchttreppen an Hotels oder sonstigen Großgebäuden, sowie als Außentreppen im Wohnungsbau Verwendung findet.The invention relates to a self-supporting elementary staircase, preferably used as an external staircase, as both Inspection stairs in industrial plants as well as fire Escape stairs to hotels or other large buildings, as well used as external stairs in residential construction.

Derartige Treppen mußten bisher stets auf jeden Anwendungs­ fall individuell abgestimmt werden. Ebenso die behördlich vorgeschriebene Verkehrslast von 5 KN/m2 lassen hier normale Standardtreppen scheitern, so daß der Bau einer solchen Treppe stets mit hohen Kosten verbunden war.Such stairs have always had to be individually tailored to each application. Likewise, the officially prescribed traffic load of 5 KN / m 2 make normal standard stairs fail, so that the construction of such stairs was always associated with high costs.

Auch die bisher bekannten Spindeltreppen, bei der sämtliche Stufen an einem zentralen Rohr befestigt sind, lassen sich nur bedingt einsetzen, da bei der Überwindung größerer Höhen die Statik hier an nicht überwindbare Grenzen stößt. Die Treppe der deutschen Patentanmeldung P 36 37 807 vermeidet zwar die genannten Nachteile, ist jedoch in ihrer Bauart noch zu materialintensiv.Even the previously known spiral staircases, in which all Steps are attached to a central tube use only to a limited extent, since overcoming greater heights the statics here reach insurmountable limits. The Avoid stairs of the German patent application P 36 37 807 Although the disadvantages mentioned, but is in their design still too material intensive.

Aufgabe der Erfindung ist es, eine Treppe für oben genannte Einsatzfälle zu schaffen, die wirtschaftlich herzustellen und zu montieren ist, gering im Materialverbrauch, sowie praktisch für jeden beliebigen Treppenlauf ohne Sonderkon­ struktion zu verwenden ist.The object of the invention is to provide a staircase for the above To create use cases that are economical to manufacture and to assemble, low in material consumption, as well practically for any stair run without special con structure is to be used.

Erfindungsgemäß wird die Aufgabe gelöst durch eine Stahlrohr­ konstruktion, welche aus den U-förmigen Verbindungsbügeln, den an den oberen Enden der Verbindungsbügel aufgesetzten Hand­ laufteilen und den an den unteren Enden der Verbindungsbügel durch Klemmverbindungen eingesetzte Trittstufen besteht.According to the invention the object is achieved by a steel tube construction, which consists of the U-shaped connecting brackets, the hand attached to the upper ends of the connecting bracket running parts and at the lower ends of the connecting bracket there are steps used by clamp connections.

Weitere Merkmale der Erfindung bestehen darin, daß nur drei Elemente, Verbindungsbügel, Handlaufteil und Trittstufe, er­ forderlich sind, um eine komplette Treppe zu realisieren und daß mit fünf Serienteilen, Verbindungsbügel, Außenhandlaufteil, Innenhandlaufteil, Trittstufe für Radien, Trittstufe für Gerade­ auslauf, jede gewünschte Treppenlaufform herstellbar ist.Further features of the invention are that only three Elements, connecting bracket, handrail part and step, he are required to realize a complete staircase and that with five series parts, connecting bracket, outer handrail part, Inner handrail section, step for radii, step for straight spout, any desired stair run shape can be produced.

Die Erfindung soll mit Hilfe der Zeichnung näher erläutert werden.The invention will be explained in more detail with the aid of the drawing will.

Fig. 1 zeigt den typischen Treppenlauf einer Wendeltreppe. Für die Herstellung dieses Treppenlaufes genügen 4 Bauele­ mente: Stufe, Verbindungsbügel, Außen- und Innenhandlaufteil. Fig. 1 shows the typical flight of stairs of a spiral staircase. 4 components are sufficient to manufacture this staircase: step, connecting bracket, outer and inner handrail part.

Fig. 2 und 3 zeigen Treppenläufe, die alle Varianten ent­ halten. Neben dem schon vorhandenen Element der Wendeltreppe, welches für alle Radienteilabschnitte des Treppenlaufes ver­ wendet wird, muß hier lediglich nur noch die Trittstufe für den Geradeauslauf eingesetzt werden, um die geraden Abschnitte der Treppenläufe damit abzudecken. Fig. 2 and 3 show stair flights, hold the variants ent. In addition to the already existing element of the spiral staircase, which is used for all radius sections of the stair run, only the step for the straight run need to be used here to cover the straight sections of the stair run.

Fig. 4 zeigt die perspektivische Darstellung zweier zusammen­ zusetzender Stufenelemente. Fig. 4 shows the perspective view of two step elements to be put together.

Fig. 5 zeigt die Trittstufe für Geradeauslauf und Fig. 6 die Trittstufe für Radien. Fig. 5 shows the step for straight running and Fig. 6 shows the step for radii.

Fig. 7 zeigt vergrößert die auf die oberen Enden der Verbin­ dungsbügel aufgesteckten Handlaufteile, sowie deren Befesti­ gung. Fig. 7 shows enlarged on the upper ends of the connec tion bracket handrail parts, and their fastening supply.

Zentrales Bauelement der Treppe ist der U-förmig gebogene Verbindungsbügel (1) aus Stahlrohr. Untereinander verbunden werden die Verbindungsbügel an den oberen Enden durch die Handlaufteile (2) und im unteren Bereich durch die Trittstu­ fen (3). Die Handlaufteile (2) bestehen aus einem ent­ sprechend der Treppenneigung gebogenen Stahlrohr mit einsei­ tig quer angeschweißter Verbindungsmuffe (5). In diese Ver­ bindungsmuffe wird von unten der Verbindungsbügel (1) und von oben das freie Ende des folgenden Handlaufteiles eingesteckt. The central component of the staircase is the U-shaped connecting bracket ( 1 ) made of tubular steel. The connecting brackets are connected to each other at the upper ends by the handrail parts ( 2 ) and in the lower area by the treads ( 3 ). The handrail parts ( 2 ) consist of a steel tube bent according to the inclination of the stairs with one-sided cross-welded connecting sleeve ( 5 ). In this Ver connection sleeve is inserted from below the connecting bracket ( 1 ) and from above the free end of the following handrail part.

Entsprechendes konstruktionsseitig vorgesehenes axiales Spiel zwischen den eingesteckten Rohrenden berücksichtigt den bei der Treppenmontage notwendigen Tritthöhenausgleich. Gewinde­ stifte (7) helfen bei der Justage und Spannstifte (8) geben der Verbindung die notwendige statische Belastungsfähigkeit. Dabei brauchen lediglich die bereits in der Verbindungsmuffe (5) vorhandenen Löcher mit der Handbohrmaschine durch das eingesteckte Rohrende durchgebohrt zu werden.Corresponding axial play provided by the construction between the inserted pipe ends takes into account the step height compensation necessary when installing the stairs. Threaded pins ( 7 ) help with the adjustment and dowel pins ( 8 ) give the connection the necessary static load capacity. All that is required is to drill the holes already in the connecting sleeve ( 5 ) with the hand drill through the inserted pipe end.

Die Trittstufen (3) bestehen aus einem Flachstahlrahmen, der an allen vier Ecken als Rohrschelle ausgebildet ist. Diese Rohrschellen greifen in den unteren Bereich zweier Verbindungs­ bügelpaare und sorgen durch Anzug der 3 bzw. 4 Rohrschellen­ schrauben für eine besonders steife Verbindung. Als Trittstufe kommen je nach Treppenlaufform zwei Stufenformen zum Einsatz. Die Geradentrittstufe (Fig. 5) für die Geradeausführung des Treppenlaufes und die Radiusstufe (Fig. 6) für die Kurvenfüh­ rung des Treppenlaufes. Die Rahmenkonstruktion der Trittstufen kann dabei durch Gitterrost, Lochblech, Tränenblech, Stein, Holz sowie durch Kunststoffbeläge ausgefüllt werden. Die Sym­ metrie der Radiusstufe macht ihre Verwendung sowohl für den Rechtsbogen als auch für den Linksbogen des Treppenlaufes mög­ lich.The steps ( 3 ) consist of a flat steel frame, which is designed as a pipe clamp at all four corners. These pipe clamps reach into the lower area of two pairs of connecting brackets and ensure a particularly rigid connection by tightening the 3 or 4 pipe clamp screws. Depending on the shape of the staircase, two steps are used as the step. The straight step ( Fig. 5) for the straight execution of the staircase and the radius step ( Fig. 6) for the curve guidance of the staircase. The frame construction of the steps can be filled with grating, perforated plate, teardrop plate, stone, wood and plastic coverings. The symmetry of the radius step makes it possible to use it both for the right-hand arch and for the left-hand arch of the flight of stairs.

Ein am Handlaufteil (2) angeschweißtes Blech (6) dient als Auf­ nahme der Geländerstäbe (4), die im unteren Bereich an der Tritt­ stufe befestigt sind. Diese Möglichkeit stellt nur eine von vielen dar. So sind auch komplette Auskleidungen durch Lochblech o.ä. denkbar.A on the handrail part ( 2 ) welded sheet metal ( 6 ) serves as a measure on the handrails ( 4 ) which are attached to the step in the lower area. This option is only one of many. Complete linings made of perforated sheet or similar are also possible. conceivable.

Durch die Einfachheit der wenigen Teile läßt sich die Treppe ohne Biege-Nacharbeit sehr schnell montieren. Spezielle Oberflächen­ behandlungen der fertigen Stahlrohr- u. Trittstufenelemente können somit vor der Montage der Treppe erfolgen, da es sich dabei um absolut fertige Einzelteile handelt. Due to the simplicity of the few parts, the stairs can be made without Assemble bending rework very quickly. Special surfaces treatments of the finished tubular steel u. Step elements can thus be done before assembling the staircase as it is absolutely finished parts.  

Geringster Materialeinsatz und Transportgewicht, größtmögliche Stabilität und einfache Montage ohne Nacharbeit machen diese Treppe zu einem besonders wirtschaftlichen Produkt. Die ein­ fache technische Formgebung, die Dominanz der gebogenen Stahl­ rohre verleihen der Treppe darüber hinaus auch ein ansprechen­ des Design.Lowest use of material and transport weight, greatest possible Stability and easy assembly without reworking make this Stairs to a particularly economical product. The one fold technical shape, the dominance of bent steel Pipes also give the stairs an appeal of the design.
